Installation InstructionsPreparation1. Before you start to use the unit, check for local codes and ordinances which may apply. It is your re-sponsibility to obtain any necessary permits.2. Read all of these installation instructions carefully. Be sure to read and understand all of the warnings.3. The unit should only be used indoors, or it should be protected from the weather.

WARNING!• Protect the unit from rain or moisture. If the electrical parts in the power unit get wet, workers may be hurt by electrical shock. The electrical parts may fail if they are wet.

CAUTION!• This unit has an electric motor that can create sparks. Don’t use the unit in an area where flammable gases may be present.

4. You will need these tools to install the unit:• A crane or lift truck that can lift the unit safely.• Shims and lag bolts.• A masonry drill and bit to drill the holes for the lag bolts.• Wrenches to fit the lag bolts.

POSITIONING THE UNIT1. Remove the shipping material and unskid the unit. You will need a crane or lift truck that can lift the unit safely.

CAUTION!Do not try to move the lift by supporting the tilt platform. One end of the tilt platform is free.

WARNING!If the unit is mounted on an unstable sur-face, it may tip over when it is in use. You may be hurt, and the unit and load may be damaged.

ELECTRICAL CONNECTIONS1. The unit has a power cord which is 10’ long (305 cm). At each location where you want to use the unit, be sure a three-prong outlet is available. Each circuit should have a 20 amp dedicated circuit breaker or fuse.

DANGER!The unit uses a power supply of 115 volts AC. This voltage can kill you. Don’t work with the electrical parts unless you are a qualified electrician.

WARNING!To avoid fire danger, be sure to provide a circuit breaker or fuse.

2. The foot switch assembly is attached to the unit by a 3’ cable (91 cm). Position the control box in a convenient location near the unit.3. Check the level of the hydraulic fluid in the tank. In order to check the level, lower the unit completely and unplug the power cord. Remove the rear cover on the unit. The tank is located below the motor and pump. The tank is normally filled through the vent plug (connected to the clear plastic vent line). To check the level, remove the vent plug. Use a dipstick to check the oil level. The oil should be 1/2’’ to 3/4’’ (13 to 19 mm) below the top of the tank. Add oil as necessary.


Testing1. Clear the area around the unit, and warn others to stay away from the unit. Remove any loose wires, lumber, or other materials which might get in the way of the unit as it raises or lowers.2. Operate the unit through its full range of travel. The unit should rise smoothly with a quiet humming sound, and lower smoothly and quietly. Raise and lower the unit a few times to check the clearances around the tilt platform.

WARNING!As the tilt platform moves up and down, “pinch points” are created at the places shown in Fig. 2. If you are standing too close to the unit when it is moving, your arm or leg may be caught in the moving parts, and you may be hurt. Stay away from the pinch points when the unit is moving.

3. If the unit is lowering too quickly or too slowly, you can change the “down speed” by adjusting the flow control.If you want the tilt platform to lower more slowly, turn the control clockwise up to 1/4 turn at a time. If you want the tilt platform to lower more quickly, turn the control counterclockwise up to 1/4 turn. Don’t move the control more than 1/4 turn at a time.

Fig. 2. Pinch Points

4. Test the unit with the rated load. If the unit does not rise, and you hear a loud squealing noise, the pressure relief valve is operating. Contact Presto for instructions.

WARNING!Don’t continue to use the unit if this hap-pens – the pump will overheat very quickly, and may be permanently damaged. Do not try to adjust the relief valve. If you change the setting on the relief valve, you may overwork the unit. This can cause the unit to fail suddenly, and you may be hurt.

5. Clean up any spilled hydraulic fluid. Spilled hydraulic oil is slippery, and may present a fire hazard. If you clean up any spilled fluid, you will be able to tell right away if the unit begins to leak.5. Figure 3 shows the safety labels on this unit. Check to be sure all of the labels are in place.

Raising the Tilt Platform1. Before raising the tilt platform, be sure all workers are clear of the unit.

WARNING!As the tilt platform moves up and down, “pinch points” are created as shown in Fig. 2. Stay away from these pinch points! Part of your body or clothing may become caught, and you may be hurt. Do not put your hands or feet under the tilt platform. Do not stand or sit on the tilt platform.

2. Before lifting, be sure the parts container is pushed up against the tilt platform, as shown in Fig. 4. Be sure the load is balanced side-to-side, as shown in Fig. 6.3. Plug in the AC cord. Be sure the cord cannot be-come caught in the moving parts as the platform raises.

WARNING!Be sure that the electrical power cord will not be pinched by the unit as it raises or lowers. If you allow the cord to be pinched, it may be broken. This can create a shock hazard. To avoid this problem, always check the position of the cord before you start to raise or lower the unit.

5. Operate the unit. Press and hold the Up button to raise the tilt platform, and Down to lower it. If the unit does not operate right away, unplug the power cord and call a qualified maintenance worker.

WARNING!This power unit contains a hydraulic pump that is capable of developing excessive pressure. A pressure relief valve is used to set the pressure at a desired level. Tamper-ing with, adjusting, modifying or removing the relief valve is extremely dangerous and is not recommended. Only a trained hydraulics technician, using a calibrated hy-draulic pressure gauge to assure the proper pressure setting is achieved, should make adjustments to the relief valve.

Moving the Unit1. Before moving the unit, always lower the tilt plat-form. You should do this even if the unit is not loaded.

WARNING!If you try to move the unit while the tilt platform is raised, the unit may be unstable. You may be hurt, and the lift or load may be damaged.

2. Unplug the power cord. Place the end over the top of the unit, so the cord does not drag.

CAUTION!As you move the unit, do not allow the power cord to drag on the floor. The cord may catch on something and stop the unit suddenly.

3. Before moving, release the floor lock.4. Always roll the unit across a stable, solid surface.

WARNING!If the floor is not stable or solid, the unit may tilt over. You may be hurt, and the unit or load may be damaged.

Maintenance andTroubleshootingAll servicing should be done by qualified personnel. Qualified personnel should be able to read and under-stand wiring and hydraulic diagrams. They should be able to troubleshoot live electrical circuits safely and in accordance with accepted practice. For safety’s sake, if in doubt, please contact your dealer or Presto Lifts Customer Service Department at (800) 343-9322.

Before servicing the unit, please read and understand all of this section and the section entitled “Operating Instructions.”

HazardsThere are several hazards you should be aware of as you service the unit:

DANGER!• The unit uses a power supply of 115 Volts AC. This voltage can kill you. Do not work on the electrical parts unless you are a qualified electrician!

WARNINGS!• As the unit moves up and down, “pinch points” are formed as shown in Fig. 2. Keep hands, feet, and loose clothing away from these pinch points. If your hand or arm or a part of your clothing is caught, you may be hurt.• Before performing any maintenance on the unit, lower the tilt platform completely. Failure to do so could result in severe personal injury.• The relief valve has been included for the protection of all of the workers who use the unit. Don’t change the relief setting! If the relief valve does not open when it should, the unit may fail. Someone may be hurt, and the unit and load may be damaged.• If the hydraulic fluid is released under high pressure, it can cause personal injury. Before you open any part of the hydraulic system, be sure to release the hydraulic pressure. You can do this by lowering the tilt platform all the way down.

• The warning labels have been included for the safety of the operator. If the labels are worn or missing, or have been painted over, replace them before releasing the lift for operation. Fig. 3 shows the safety markings on this unit.

Routine Periodic MaintenanceEvery month:Visually inspect the pins and bushings at each end of the cylinder(s) for signs of wear. Also check the pivot pins at both sides of the tilt platform. If any of these parts are worn, contact Presto for repair instructions.• Apply oil or WD-40 to the parts listed in the last step.Note: Although the busings are “lifetime lubricated” Teflon® bushings, their performance may be ex-tended by additional periodic lubrication.• Check the level and appearance of the hydraulic fluid. in order to check the level, lower the unit completely and unplug the power cord. Remove the rear cover on the unit. Lower the platform. Remove the red plastic vent plug on top of the hydraulic tank, and use a dipstick to check the oil level. When the platform is fully lowered, the oil should be about 1/2 to 3/4 inches below the top of the tank. Add oil if necessary. Change the oil if it has darkened, or feels gritty or sticky.

CAUTION!It is important to use hydraulic fluid with the correct grade and properties. See the hydraulic oil specification in Fig. 17 of this manual.

Every six months or 500 hours ofoperation, whichever comes first:• Check all of the hydraulic fittings and hoses, and tighten the connections if necessary. Sometimes the fittings can be worked loose by the vibrations from the power unit.

WARNING!If a hydraulic fitting becomes loose, or if a hydraulic hose breaks, the hydraulic fluid may escape from the system under pres-sure. If the tilt platform is raised when this happens, it can drop quickly. Someone may be hurt, or the unit or load may be damaged. To avoid this problem, inspect all of the hydraulic hoses and fittings regularly, and replace them if they are worn or damaged.


• The clear plastic vent line(s) and the cylinder rod(s) should be free of hydraulic fluid. If you find much fluid in either place, the cylinder seals may be leaking. (It is also possible the tank may be overfilled.) If the worn parts must be replaced, see the section on “Repacking the Cylinder(s).”• Disassemble the down valve as shown in Fig. 9. Blow the valve plunger clean with compressed air. Reas-semble the valve and reinstall it.• Drain and discard the hydraulic fluid. The suction filter is in the tank, at the point where the suction line runs out to the pump. Unscrew the hydraulic line, then remove the filter. Blow the filter clean with compressed air. Reinstall the filter in the tank and reassemble the hydraulic line.• Refill the tank with new hydraulic fluid.

CAUTION!If you continue to use fluid after it has “worn out,” the moving parts in the system will wear more quickly.

• Be sure all of the warning labels are in position and legible. The warning labels are intended to protect your workers. If the labels are missing, or if they have been painted over, replace them.

Repacking the CylinderThe lift in the SRT unit may use several different types of cylinders. To order a repacking kit and to receive instructions, please call the Presto Parts Department at (800) 343-9322. When ordering, specify the model number and serial number of the unit.
